Albright Visitor Center, Mammoth Hot Springs · Yellowstone National Park, WY
Yellowstone was established on March 1, 1872, and covers 3,472 square miles, mostly in Wyoming with edges in Montana and Idaho. It holds more than 10,000 hydrothermal features, including over 500 active geysers, more than half the world's total. Visitors drive between geyser basins, the hot spring terraces at Mammoth and wide valleys known for wildlife. The park is open all year, but from early November to late April most roads close to cars; the road from Mammoth Hot Springs to the Northeast Entrance stays open. Entry is $35 per vehicle or $20 per person for seven days.
